[0002] In order to improve the comfort of tooth brushing and reduce the stimulation of toothbrush bristles to the gums, thereby reducing the problem of gum bleeding when the user brushes teeth, the existing toothbrush technology usually adopts the method of reducing the diameter of the bristles and increasing the amount of bristles to improve the softness of the bristles and increase the contact area of the bristles with the oral cavity, thereby reducing the action strength of the bristles to the gums during tooth brushing and achieving gingiva protection. However, this method usually causes the bristles to be too soft, which reduces the pressure of the bristles on the teeth, thereby reducing the cleaning force, and increases the amount of bristles, which increases the overall density of the bristles, causing the bristles to accumulate water and not dry easily, and easily breeding bacteria.

[0022] Embodiment one: As Figures 1 to 3As shown, the present application provides a flexible gum protection toothbrush, comprising a brush head support 1, a deformation part 2 arranged on the brush head support 1, and a cleaning part 3 arranged on the deformation part 2, wherein the cleaning part 3 comprises a plurality of bristle bundles 31, the brush head support 1 is provided with a tooth-side 11, the deformation part 2 and the cleaning part 3 are arranged corresponding to the tooth-side 11, and the deformation part 2 can be concave or convex relative to the tooth-side 11, thereby driving the cleaning ends 311 of the bristle bundles 31 to be gathered or diverged along the central axis L of the deformation part 2 corresponding to the concave or convex deformation of the deformation part 2.

[0023] In this embodiment, the tooth-side 11 of the brush head support 1 refers to the side of the brush head support 1 facing the oral cavity during tooth brushing, the deformation part 2 is arranged close to the tooth-side 11 of the brush head support 1, and the cleaning part 3 for cleaning the oral structure such as teeth is arranged on the deformation part 2, wherein the cleaning part 3 comprises a plurality of bristle bundles 31 connected to the deformation part 2, and each bristle bundle 31 is provided with a fixed end 312 connected to the deformation part 2 and a cleaning end 311 away from the deformation part 2 for cleaning; by arranging the elastically deformable deformation part 2 on the brush head, the deformation part 2 can be concave deformed relative to the tooth-side 11 towards the inside of the brush head support 1 under the action of the forward force F during tooth brushing, while driving the cleaning ends 311 of the bristle bundles 31 to be gathered towards the central axis L of the deformation part 2, and forming a cleaning surface 32 with increased bristle density and reduced area, thereby reducing the pressure intensity of the bristles on the gums to prevent gum bleeding, while increasing the pressure intensity of the bristles on the teeth to improve the cleaning strength; in addition, when the forward force F acting on the deformation part 2 is reduced or removed, the deformation part 2 as a whole can be convex deformed relative to the tooth-side 11 away from the brush head support 1 to restore to the initial state, while driving the cleaning ends 311 of the bristle bundles 31 to diverge outward along the central axis L of the deformation part 2 to increase the gap between the bristle bundles 31, which is beneficial to the drainage of water and the ventilation and drying of the bristles, effectively avoids bacterial growth, improves the hygiene performance of the brush head, prolongs the service life of the toothbrush and ensures the safe use of the user.

[0024] Specifically, as shown in FIG. 1, the tooth-side 11 of the brush head support 1 is provided with a deformation part 2, and the deformation part 2 is arranged corresponding to the tooth-side 11. Figure 3As shown, when the deformation part 2 is in the initial state, at this time the deformation part 2 is not subjected to external force, and the deformation part 2 protrudes outward relative to the proximal tooth side 11 of the brush head support 1, at this time the deformation surface 20 on the deformation part 2 is an outward convex surface, so that each brush bundle 31 is dispersed in different directions along the contour of the outward convex surface, thereby making the cleaning part 3 in a divergent state, at this time each drainage flow channel 33 can be formed on the side of each brush bundle 31, and each drainage flow channel 33 extends along the contour of the outward convex surface respectively, through the outward convex surface, it is beneficial to guide the residual water in the brush head after washing to be discharged through the drainage flow channel 33, at the same time, when the toothbrush is in a natural ventilation environment, the ventilation gap 34 communicated with the drainage flow channel 33 is generated between each brush bundle 31 in the divergent state, through the ventilation gap 34, air flow can also be strengthened, which is beneficial to the drying of the brush, effectively avoids the breeding of bacteria, thereby improving the hygiene performance of the brush head, prolonging the service life of the toothbrush and ensuring the safe use of the user.

[0025] As shown, Figure 3 During the tooth brushing process, the cleaning part 3 subjected to the positive action force F applied by the oral structure can drive the deformation part 2 to produce a concave deformation relative to the proximal tooth side 11 towards the inner side of the brush head support 1, so that the deformation part 2 is switched from the initial state to the tooth brushing state, at this time an inner concave surface is formed on the deformation part 2, so that the cleaning end 311 of each brush bundle 31 is gathered towards the central axis L of the inner concave surface, thereby making the cleaning part 3 switched to a gathering state, at this time the cleaning end 311 of each brush bundle 31 is concentrated in a cleaning surface 32 with increased density and reduced area, during the tooth brushing process, the contact area between the brush and the gums is reduced through the cleaning surface 32, thereby reducing the action strength on the gums, effectively preventing gum bleeding, at the same time, the cleaning surface 32 increases the action strength on the teeth, thereby enhancing the cleaning strength on the teeth and improving the tooth cleaning efficiency; when the tooth brushing is finished, the positive action force F applied by the teeth to the cleaning part 3 is removed, at this time, the deformation part 2 can automatically rebound and restore to the initial state under the action of its own elastic force, so as to restore the cleaning part 3 to the divergent state.

[0026] Further, the deformation part 2 is arranged in adaptation with the inner contour of the brush head support 1, the projection surface of the deformation surface 20 on the deformation part 2 can be circular or elliptical, which is not specifically limited here; as an optional embodiment of the present scheme, as shown in Figure 2 The deformation part 2 extends along the length direction of the brush head support 1 and can form an elliptical deformation surface 20.

[0027] Further, as an optional embodiment of the present scheme, as shown in Figure 3As shown, when the deformation surface 20 is subjected to force to produce elastic deformation, the concave height of the deformation surface 20 gradually decreases from the central axis L of the deformation portion 2 to both sides, which is conducive to forming a concave surface and ensuring that the cleaning end 311 of each bristle bundle 31 is gathered towards the central axis L of the deformation portion 2; further, the concave height of the deformation surface 20 is the normal displacement of the deformation surface 20 under the action of the pressing force during brushing, wherein the maximum concave height of the deformation surface 20 can be set based on Hooke's law according to the elastic modulus of the deformation portion 2 and the pressing force applied by the user during brushing, for example, in the usual case, the pressing force of the user during regular brushing is 2-5N, and the maximum concave height of the deformation surface 20 can be set to 1-3mm; when the user brushes gently, the pressing force is 0.5-2N, and the maximum concave height of the deformation surface 20 can be set to 0.3-1mm, which is conducive to avoiding damage to the gums.

[0028] Further optionally, the maximum concave height of the deformation surface 20 can be set to 1mm, 1.5mm, 2mm or 3mm when the user brushes regularly, and the maximum concave height of the deformation surface 20 can be set to 0.5mm or 1mm when the user brushes gently.

[0029] As another optional embodiment of the present scheme, as shown in Figure 3 The connecting portion 25 is provided between the deformation portion 2 and the proximal tooth side 11 of the brush head holder 1, which enhances the connection strength of the deformation portion 2 in the brush head holder 1, and when the deformation portion 2 is deformed inwardly or outwardly relative to the proximal tooth side 11, the connecting portion 25 can inhibit the deformation and pulling of the edge of the deformation portion 2 relative to the brush head holder 1 to some extent, which is conducive to enhancing the structural strength of the deformation portion 2 and prolonging its service life.

[0030] As an optional embodiment of the present scheme, the deformation portion 2 is made of soft material capable of elastic deformation, so that the deformation portion 2 can quickly and accurately produce controllable concave deformation under force, and quickly recover to a convex shape when the external force disappears, ensuring that the deformation surface 20 of the deformation portion 2 as a whole produces elastic deformation of inward concave and outward convex, thereby accurately controlling the switching of the bristle bundle 31 between the diverging state and the gathering shape, further optimizing the balance between gum protection and cleaning effect; secondly, the soft material has excellent elastic memory function, which can withstand long-term repeated stress in daily brushing process, maintain stable elastic deformation cycle, avoid deformation ability attenuation caused by material fatigue or plastic deformation, and ensure that the bristle bundle 31 can always be reliably gathered in the brushing state to maintain sufficient cleaning pressure and reduce gum irritation, and stably dispersed in the initial state to ensure the drainage and drying of the bristles, thereby improving the durability of the toothbrush.

[0031] Further, the soft material capable of producing elastic deformation at least includes one of TPE, TPU and silica gel, and the Shore hardness of the deformation part 2 is greater than 90A, so that the deformation part 2 can produce stable and controllable concave deformation when stressed, and will not cause excessive deformation of the bristles due to the softness of the material itself, which can damage the oral cavity structure or cause no resistance when pressed.

[0032] Preferably, in the production process, the deformation part 2 can be made of the above-mentioned soft material by integral molding, so as to increase the structural strength and deformability of the deformation part 2, and quickly and accurately produce controllable concave deformation.

[0033] As an optional embodiment of the present scheme, each of the bristle bundles 31 is integrally formed with the deformation part 2; alternatively, each of the bristle bundles 31 and the deformation part 2 can be made into a whole structure by integral injection molding or die molding process, so that the root of each bristle bundle 31 and the deformation part 2 form a seamless connection, avoiding the loosening, falling or relative displacement of the bristles and the deformation part 2 due to the adhesion, clamping and other ways in the split design of the traditional bristles and the implantation surface 21. In actual application, when the deformation part 2 is pressed to produce concave deformation or rebound to produce convex deformation in the state of brushing teeth, the integrally formed connection structure ensures that each bristle bundle 31 can be switched to the gathering state or the diverging state synchronously and uniformly with the concave or convex of the deformation part 2, further optimizing the consistency and synchronization of each bristle bundle 31 in the transformation between different states following the deformation of the deformation part 2, and improving the accuracy of brushing and the effect of gum protection.

By protruding from the brush head support 1, the deformation part 2 can be in flexible contact with the oral structure during tooth brushing, so as to protect the oral structure and further optimize the user's tooth brushing experience.

[0036] Further optionally, as Figure 2 As shown, the brush head support 1 comprises a first support 101 and a second support 102 arranged oppositely, and the first support 101 and the second support 102 are at least partially arranged in an arc shape to form an elliptical assembly cavity structure, so as to facilitate the processing and forming of the deformation part 2; further optionally, the first support 101 and the second support 102 combine to form a U-shaped support.

[0037] Further optionally, Figure 7 Another optional embodiment of the present scheme is shown, and each of the bristle bundles 31 is arranged on the deformation part 2. Specifically, the cleaning part 3 comprises a first bristle bundle group 301, a second bristle bundle group 302 and a third bristle bundle group 303 arranged in sequence from inside to outside on the deformation part 2, and the first bristle bundle group 301, the second bristle bundle group 302 and the third bristle bundle group 303 each comprise a plurality of bristle bundles 31. The number of bristle bundles 31 in the first bristle bundle group 301, the second bristle bundle group 302 and the third bristle bundle group 303 can be adjusted according to the arrangement position of the bristle bundles 31 on the deformation part 2.

[0038] Further, as Figure 7As shown, each of the bristle tufts 31 of the first tuft group 301 is distributed along the central axis L of the deformation portion 2, the first tuft group 301 comprises a first tuft 301a, a second tuft 301b, a third tuft 301c, a fourth tuft 301d and a fifth tuft 301e, the fifth tuft 301e is provided with a plurality of and is uniformly distributed along the central axis L of the deformation portion 2, the first tuft 301a and the second tuft 301b are symmetrically arranged on both sides of the fifth tuft 301e, the third tuft 301c and the fourth tuft 301d are symmetrically arranged on both sides of the fifth tuft 301e, and the third tuft 301c and the fourth tuft 301d are located at the periphery of the first tuft 301a and the second tuft 301b; each of the bristle tufts 31 of the second tuft group 302 is distributed along a first elliptical path S1 in the deformation portion 2, the first tuft 301a and the second tuft 301b are respectively arranged at both ends of the major axis of the first elliptical path S1, the second tuft group 302 comprises a first left tuft 302a and a first right tuft 302b symmetrically arranged on the first elliptical path S1, the first left tuft 302a and the first right tuft 302b are provided with a plurality of in one-to-one correspondence, each of the first left tufts 302a is uniformly distributed in the deformation portion 2 along the central axis L on the left side of the first elliptical path S1, and each of the first right tufts 302b is uniformly distributed in the deformation portion 2 along the central axis L on the right side of the first elliptical path S1.The third tuft group 303 is distributed along a second elliptical path S2 in the deformation part 2, and the second elliptical path S2 is located at the periphery of the first elliptical path S1, the third tuft 301c and the fourth tuft 301d are respectively arranged at both ends of the long axis of the second elliptical path S2, the second left tuft 303a and the second right tuft 303b are symmetrically arranged on the second elliptical path S2, and a plurality of second left tufts 303a and a plurality of second right tufts 303b are correspondingly arranged, each second left tuft 303a is uniformly distributed on the left side of the central axis L of the deformation part 2 along the second elliptical path S2, and each second right tuft 303b is uniformly distributed on the right side of the central axis L of the deformation part 2 along the second elliptical path S2, which optimizes the arrangement of each tuft 31 on the deformation part 2. When the deformation part 2 is in the concave tooth brushing state, the first left tuft 302a and the first right tuft 302b, the second left tuft 303a and the second right tuft 303b correspondingly gather along the vertical direction of the central axis L of the deformation part 2 to the central axis L of the deformation part 2, and each first left tuft 302a and each second left tuft 303a are staggered, that is, any first left tuft 302a is arranged between two adjacent second left tufts 303a. Similarly, each first right tuft 302b and each second right tuft 303b are staggered, which can increase the bristle density and uniformity of the cleaning surface 32, avoid sparse bristles and local density increase, and further ensure the improvement of toothbrush cleaning strength and the optimization of user experience. It should be noted that the fixed end 312 of each tuft 31 is distributed along different paths to form the arrangement of the first tuft group 301, the second tuft group 302 and the third tuft group 303.

[0039] Optionally, as shown in Figure 7 The length of the short axis of the first elliptical path S1 is 1 / 2 of the length of the short axis of the second elliptical path S2, the difference between the length of the long axis of the second elliptical path S2 and the length of the long axis of the first elliptical path S1 is the sum of the distance between the first tuft 301a and the third tuft 301c and the distance between the second tuft 301b and the fourth tuft 301d; further optionally, the distance between the first tuft 301a and the third tuft 301c is equal to the distance between the third tuft 301c and the fifth tuft 301e closest to the third tuft 301c, and the distance between the second tuft 301b and the fourth tuft 301d is equal to the distance between the fourth tuft 301d and the fifth tuft 301e closest to the fourth tuft 301d.

[0040] Optionally, as shown in Figure 3 And Figure 7As shown, when the deformable part 2 is in the initial outward convex state, each of the bristle bundles 31 is perpendicular to the outward convex surface of the deformable part 2; when the deformable part 2 is in the inward concave brushing state, the bristle bundles 31 of the first bristle bundle group 301 sink down along the central axis L of the deformable part 2, and the bristle bundles 31 of the second bristle bundle group 302 and the bristle bundles 31 of the third bristle bundle group 303 converge toward the central axis L of the deformable part 2, so that a slightly concave cleaning surface 32 is formed on the cleaning part 3, so that the cleaning surface 32 fits the tooth surface contour better, thereby making the bristles maintain uniform contact with the tooth surface and reducing the cleaning blind spots in the teeth.

[0041] Example 2: Figure 5 This paper presents another optional embodiment of the present solution. The difference between this second embodiment and the first embodiment is that the deformable part 2 is made of a soft material capable of elastic deformation. The brush head support 1 also includes a partition 13 located on one side of the deformable part 2. The partition 13, the brush head support 1, and the deformable part 2 enclose a clearance cavity 14. In this embodiment, the clearance cavity 14 provides sufficient concave deformation space for the soft deformable part 2, reducing its deformation resistance and thus enhancing its deformation capability. This, in turn, strengthens the gathering effect of the cleaning part 3, thereby improving the toothbrush's cleaning power. Furthermore, by providing the clearance cavity 14, the material usage of the brush head support 1 is reduced, facilitating a lighter toothbrush and improving handheld comfort. Additionally, in actual production, the clearance cavity 14 can be directly formed by adjusting the distance between the partition 13 and the deformable part 2, eliminating the need for additional assembly steps. This shortens the production process and improves toothbrush production efficiency.

[0042] Further optional, such as Figure 5 As shown, the thickness of the deformable part 2 is less than the thickness of the brush head bracket 1, so as to ensure that the relief cavity 14 has sufficient space in the brush head bracket 1.

[0043] As another optional embodiment of this solution, the partition 13 can be configured as a partition plate, and the brush head bracket 1 is also provided with a wrapping part 15 located outside the partition plate. The wrapping part 15 covers the partition plate to improve the aesthetics of the toothbrush and further optimize the user experience.

[0044] Example 3: Figure 6An optional embodiment of the elastic gingiva protection toothbrush in the scheme is shown, and the difference between the third embodiment and the first and second embodiments is that the deformation part 2 is made of hard material capable of elastic deformation; the third embodiment improves the material of the deformation part 2, sets the hard elastic deformation part 2, improves the functionality and applicability of the elastic gingiva protection toothbrush, and also improves the deformation precision of the deformation part 2, so that the concave-convex deformation of the deformation surface 20 in the deformation part 2 is more controllable and accurate, and the gathering state or diverging state of each bristle bundle 31 better adapts to the user's brushing force strictly synchronously, further improving the controllability of the toothbrush cleaning effect, and the gingiva protection effect and brushing comfort; secondly, the hard elastic material has a higher elastic modulus, which can reduce the stress load borne by the hard deformation part 2, effectively avoid the accumulation of plastic deformation of the deformation part 2 due to long-term repeated deformation, prevent the thickness reduction and concave-convex deformation attenuation of the deformation part 2 under long-term use, and thus prolong the service life of the deformation part 2; in addition, the hard deformation part 2 can improve the connection strength and stability of the brush head support 1, reduce the risk of separation of the deformation part 2 and the brush head support 1 in long-term use, and thus improve the service life and reliability of the toothbrush.

[0045] Further, the hard material capable of elastic deformation at least includes one of metal material and plastic material; in the actual production process, the adaptability and functionality of the toothbrush to different use scenarios can be enhanced by improving the manufacturing material and process of the hard deformation part 2, and the limitations of traditional toothbrushes in performance, cost and application range are solved; it should be noted that the thickness of the hard deformation part 2 can be adjusted and set according to the material selected in actual production and its elastic modulus and the preset recess height, which is not limited here.

[0046] Optionally, the metal material includes pure metal or alloy, for example, the metal material can be set as one of spring steel, titanium alloy, nickel-titanium shape memory alloy, etc.; when the deformation part 2 is made of metal material to form a metal deformation part 2, the metal deformation part 2 is not prone to plastic deformation or fracture on the basis of ensuring the concave-convex deformation of the deformation part 2 relative to the brush head support 1, ensuring the structural stability of the toothbrush in long-term use, so that the toothbrush can adapt to the scene of heavy brushing, for example, orthodontic patients need to apply a pressing force of 5-8 N when cleaning the bracket; secondly, the metal deformation part 2 can improve the resistance to high-temperature disinfection and strong acid and alkali environment, and is not prone to aging, swelling or deformation failure, and can adapt to surgical toothbrushes that need to be repeatedly sterilized in medical scenarios.

[0047] Further, in order to avoid the problem that the metal deformation part 2 is easy to be corroded and oxidized when it is long-term exposed to water, the surface of the metal deformation part 2 can be waterproofed, for example, coated with a waterproof layer, or the metal deformation part 2 can be made of a metal material with waterproof property, so as to improve the stability of the metal deformation part 2, prolong the service life of the metal deformation part 2, improve the safety of the toothbrush, and protect the oral health of the user.

[0048] Alternatively, the plastic material at least includes one of shape memory polymer SMP, glass fiber reinforced thermoplastic elastomer GF-TPE, polycarbonate PC, etc. These plastic materials have the advantages of easy processing and low cost. The deformation part 2 can be integrally injection molded, which greatly simplifies the processing technology of the deformation part 2, is conducive to large-scale production, and reduces production costs. It should be noted that in the actual toothbrush production process, the medium elastic modulus and moderate deformation amplitude can be achieved by adjusting the corresponding plastic composition and formula, so that the deformation part 2 can adapt to the actual application of the toothbrush. Here, the composition and ratio of the plastic material are not specifically limited.

[0049] Further, the deformation part 2 is provided with a plurality of arranged bristle holes 22, and each bristle bundle 31 is correspondingly arranged in each bristle hole 22. Specifically, the corresponding bristle holes 22 are arranged in the hard elastic deformation part 2 along the thickness direction of the brush head support 1. Each bristle hole 22 is implanted in the bristle hole 22 with a predetermined interval, angle and depth. Each bristle hole 22 provides a deformation guide track for each bristle bundle 31. When the hard deformation part 2 is deformed concave-convex under the force of brushing, the inner wall of the bristle hole 22 can guide the root of the bristle bundle 31 to move synchronously with the deformation part 2, and drive the cleaning end 311 of the bristle bundle 31 to converge or diverge along the central axis L of the deformation part 2. This avoids the traditional scattered implantation type bristle bundle 31 which can converge synchronously along the central axis L of the deformation surface 20, forming a continuous cleaning surface 32, ensuring that the force on each area of the tooth surface is uniform, and further improving the cleaning coverage.

[0050] Alternatively, each bristle bundle 31 can be a fiber bristle bundle 31. In actual production, the bristle bundle 31 can be implanted into the corresponding bristle hole 22 by combining the copper sheet implantation process or the copper sheet-free implantation process. Then, the hard deformation part 2 with the processed bristle hole 22 is assembled on the bristle support with a predetermined bending degree, so that the hard deformation part 2 is arranged in the initial state of outward convex on the bristle support. When the cleaning part 3 is subjected to a positive force F, the hard deformation part 2 can be deformed concave relative to the near tooth side 11 towards the inside of the brush head support 1, and when the positive force F is removed or reduced, the hard deformation part 2 rebounds to the initial state of outward convex.

[0051] As an optional embodiment of the present scheme, as shown in Figure 8 andFigure 9 As shown, each of the bristle bundles 31 can be implanted into each of the bristle implantation holes 22 using a copper-free bristle implantation process. Specifically, each of the bristle implantation holes 22 has a heat-fusion part 23 on its inner and / or outer sides. The heat-fusion part 23 is made of plastic, and the bristle bundle 31 is fixed in the bristle implantation hole 22 by heat-fusion through the heat-fusion part 23. In this embodiment, as shown... Figure 9 As shown, each of the hair implantation holes 22 has a corresponding heat-melting part 23 on its inner side. The heat-melting part 23 can be a hollow plastic sleeve inserted into the hair implantation hole 22. Then, the bristle bundle 31 is inserted into the plastic sleeve, and the plastic sleeve is heated and melted to fix the bristle bundle 31 in the hair implantation hole 22; or, as... Figure 8 As shown, the deformable part 2 has a heat-melting part 23 on its outer wall facing the distal tooth side 12. Several heat-melting parts 23 are provided around each of the hair implantation holes 22. In this case, the heat-melting part 23 can be a plastic column. Then, the bristle bundle 31 is inserted into the hair implantation hole 22, and the plastic column is heated and melted to fix the bristle bundle 31 in the hair implantation hole 22. This embodiment uses a copper-free hair implantation process, directly fixing the bristle bundle 31 through the heat-melting part 23, avoiding the problem of metal residue. Meanwhile, the plastic hot-melt part 23 poses no risk of heavy metal migration, thus improving the hygiene and safety of the toothbrush. Secondly, after the material of the hot-melt part 23 is heated and melted, it can penetrate into the micro-gaps on the bristle surface. When the hot-melt material cools, it can tightly fix the bristle bundles 31 in the bristle implantation holes 22, greatly improving the connection strength and structural strength of the bristle bundles 31, effectively preventing bristle loss. Furthermore, this copper-free bristle implantation process requires no additional glue, avoiding bristle loss problems caused by glue aging, yellowing, or hydrolysis, thus extending the toothbrush's lifespan. It should be noted that when the rigid deformable part 2 is made of plastic, the melting point of the hot-melt part 23 is lower than that of the rigid deformable part 2 to ensure the structural integrity of the rigid deformable part 2 and prevent the rigid deformable part 2 from melting simultaneously when the hot-melt part 23 is heated and melted.

[0052] As an optional embodiment of this solution, in order to enhance the deformation capability of the deformable part 2, such as... Figure 6As shown, the brush head support 1 is further provided with a separation part 13 on one side of the deformation part 2, and a clearance cavity 14 is formed among the separation part 13, the brush head support 1 and the deformation part 2; in this embodiment, along the thickness direction of the brush head support 1, the deformation part 2, the clearance cavity 14 and the separation part 13 are sequentially distributed inside the brush head support 1 from the proximal tooth side 11 to the distal tooth side 12, the clearance cavity 14 provides clearance for the recess deformation of the deformation part 2, so as to ensure that the deformation part 2 has sufficient deformation space, thereby improving the recess deformation ability of the deformation part 2, enhancing the gathering effect of the cleaning part 3, and thus improving the cleaning ability of the toothbrush; secondly, by providing the clearance cavity 14, the material amount of the brush head support 1 is reduced, so as to facilitate the light weight of the toothbrush and improve the hand holding comfort; in addition, in the actual production process, the clearance cavity 14 can be directly formed by adjusting the distance between the separation part 13 and the deformation part 2, without the need for additional assembly steps, which is beneficial to shorten the production process and improve the production efficiency of the toothbrush.

[0053] As another optional embodiment of the present scheme, the brush head support 1 is further provided with a wrapping part 15 on one side of the separation part 13, the wrapping part 15 is arranged towards the outside of the toothbrush, so as to shield the separation part 13, thereby improving the appearance of the toothbrush.

[0054] The above is only an embodiment to further illustrate the technical content of the present application, so that the reader can more easily understand, but it does not mean that the embodiments of the present application are limited to this, any technical extension or re-creation made according to the present application is protected by the present application. The protection scope of the present application is subject to the claims.
